Laser of the Haptic-Optic Junction to Fix a Tilted Yamane Intrascleral-Fixated Lens

Purpose: To report a case of tilted sutureless intrascleral fixated IOL, emphasizing its management with 23-gauge laser to strengthen the haptic-optic junction. Methods: Case report. Results: A 27-year-old man was referred for treatment of traumatic cataracts in his left eye. He underwent pars plana vitrectomy, lensectomy, membrane peel, and capsulectomy without complications. Five days after the surgery, he developed ocular hypertension that ultimately required insertion of an Ahmed glaucoma valve in the left eye. 16 months after the initial procedure, the patient underwent secondary lens implantation with a CT Lucia 602 IOL in the left eye using the Yamane technique. The day following surgery, the patient presented with a significantly tilted lens. Three weeks later, the patient underwent surgery for IOL repositioning. The manipulation of the haptics was ineffective in repositioning the IOL. The temporal sclerotomy was removed and a 23-gauge probe was used to laser both optic-haptic junctions while a light pipe held the lens in place. The tilt was corrected, and visual acuity improved to 20/40 at one year follow-up. Conclusions: Successful repositioning of tilted sutureless intrascleral fixated IOLs can be achieved using 23-gauge laser reinforcement at the haptic-optic junction. Consideration could be made to perform this laser at the time of implantation as a prophylactic approach to mitigate tilt and reduce the risk of reoperation.

Study of visual outcome and complications of primary and secondary retropupillary iris claw lens implantation in absence of adequate capsular support

This study was conducted to assess and compare the visual outcome and complications of retropupillary iris claw lens implantation in absence of adequate capsular support.This prospective, comparative, intervention, was conducted. All the patients who reported ophthalmology indoor department were divided into two groups. In 1 group patients with IMSC/MSC/Traumatic cataract/Repaired corneal tear with traumatic cataract/Subluxated IOL in which primary retropupillary iris claw lens implantation was done in the department of Ophthalmology through SICS/Phacoemulsificstion were categorised. In 2 group patients with Aphakia in which cataract surgery was performed through SICS/Phacoemulsification and were left aphakic due to PCR in the department of Ophthalmology, JLN Medical College & Hospital and outside indoor patients at various ophthalmology centres. In primary RPICL in 23(76.7%) patients found to be BCVA between 6/36 to 6/18 and in secondary RPICL 26(86.7%) patients found to be BCVA between 6/12 to 6/6. In primary cases RPICL ovalisation of pupil in 6(20%), tilted IOL with raised IOP in 3(10%) optic capture in 3(10%), iridodialysias in 3(10%), bullous keratopathy in 3(10%). In secondary RPICL optic capture in 2(6.67%), CME with raised IOP in 1(3.33%), ovalisation of pupil in 1(3.33%) was found. Results of present study suggest that secondary cases (group II) showed better visual outcome and lesser complications when compared with primary cases (group I) after retropupillary iris claw lens implantation.

Visual Outcomes of Secondary Lens Implants in Children with Different Etiologies

Aim: This study investigated visual outcomes and factors that impact vision in children receiving secondary Intraocular Lens (IOL) implants. Methods: Children who had traumatic or congenital cataracts and underwent secondary lens implantation for aphakia at Drashti Netralaya between 2000 and 2019 were retrospectively examined. We included all the eyes with secondary implants for aphakia correction with placement either in the bag or sulcus or through scleral fixation. We obtained data from electronic medical records and analyzed using SPSS 22 through descriptive analysis, cross tabulation and t test. We evaluated visual outcomes among different patients. Results: Our cohort consisted of 84 eyes (mean age: 7.88 ± 6.07 years). Of the 84 eyes, 24 (28.6%) and 60 (71.4%) were female and male patients, respectively and 32 (38.1%) had traumatic cataract. We observed significant improvements in vision following lens implantation (p=0.000). Those with nontraumatic cataracts exhibited better outcomes that did the traumatic cataract group (p=0.004). Corneal opacity caused comorbidities in the traumatic group (14/52, 14.29%). Visual outcomes significantly improved in young patients and were not affected by other variables. Conclusion: Secondary lens implantation significantly improved vision in aphakic children. Young patients and those with nontraumatic cataracts demonstrated more favorable visual outcomes.

Visual outcomes of secondary lens implants in children with different etiologies

There are several available options for the demanding surgical correction of paediatric aphakia without sufficient capsular support. The literature suggests the implantation of a transscleral fixated posterior chamber-intraocular lens (PCIOL), an intrascleral fixated PCIOL, an iris-sutured intraocular lens (IOL), or an anterior chamber iris-claw IOL. We searched for reports on the management of paediatric aphakia in case of inadequate capsular support that delineated the diverse surgical approaches and their postoperative results. Analysis demonstrated that different complications can be encountered depending on IOL placement technique, such as suture rupture, IOL dislocation, secondary glaucoma, endophthalmitis, vitreous hemorrhage, and endothelial cell loss. However, it was shown that various IOL designs have similar visual outcomes. Taking into consideration the advantages and disadvantages of each surgical technique, ophthalmic surgeons can determine the safest and most efficien...

Flanged intraocular lens (IOL) implantation with scleral pockets - A modification of flanged IOL technique (E-Flanged IOL) for secondary lens implantation.

The current technique for implanting flanged intraocular lens (IOL) suffers from complications like haptic exposure and tilting of the implanted IOL. We describe a modification of the currently described technique to obviate its shortcomings. Five eyes of five patients with a minimum of 1 year of follow-up were included. In this technique, two scleral pockets were made nasal and temporal to embed the flanged haptics. The primary outcome measure was the improvement in visual acuity (VA) postoperatively and the secondary outcome measures were postoperative complications. The primary objective of this current modification is to simplify the surgical technique for secondary IOL implantation and make it more replicable and predictive. The mean age of the patients was 19.44 years. The mean preoperative VA was 0.44 logMAR which improved to 0.26 logMAR at the 6-week postoperative visit. The mean follow-up was 496+/- 80 days. The maximum follow-up was 647 days. There were no postoperative complications such as haptic exposure, hypotony, or IOL tilt in any cases. The new E-flanged IOL technique has good visual outcomes and does not have postoperative complications. It has less intraoperative manipulation and complications.

Comparison of visual acuity in primary and secondary iris claw implantation in western Maharashtra

A potential complication of cataract surgery is posterior capsular rent, where PCIOL can’t be implanted. Primary Iris claw implantation means that the IC-IOL is implanted in the same setting after cataract removal. While secondary Iris claw lens implant is done in an aphakic eye without capsular support and post cataract surgeries when the eye is left aphakic. To compare the visual outcome in cases of primary and secondary iris claw lens implantation after cataract surgery.This was a hospital-based Prospective Interventional Longitudinal study,conducted on patients in a tertiary care centre, in Western Maharashtra from September 2018 to August 2020. 31 eyes underwent primary iris claw implant and 19 underwent secondary iris claw implant. Highly significant difference in visual acuity preoperatively due aphakia among subjects who underwent secondary iris claw implantation (p=0.000) was seen. Highly significant difference in visual acuity post operatively till 15 days was also seen due to less corneal oedema& inflammation in patients who underwent secondary iris claw implantation. No significant difference in visual acuity was seen on day 40 as lens was put in both the groups and the signs of inflammation had reduced (p=0.759).Overall visual outcome after 40 days is comparable in primary and secondary cases. It is better to do a primary retro fixated iris claw implantation, as in case of a secondary implant the patient will have undue anxiety, to undergo a second surgery along with increased financial burden and patient can develop complications due to aphakia.

Secondary Sutureless Posterior Chamber Lens Implantation with Two Specifically Designed IOLs: Iris Claw Lens versus Sutureless Trans-Scleral Plugs Fixated Lens.

Background. The management of patients with aphakia and/or lack of capsular support remains debated. The sutureless posterior chamber IOL (PCIOL) fixation is a very useful surgical option. The purpose of the study was to compare the early outcomes as well as post-operative best corrected visual acuity, refractive errors and complications of two different techniques of sutureless PCIOL secondary implantation. Methods. Patients who underwent secondary implantation from December 2019 to January 2021 in the Department of Ophthalmology of Creteil Hospital, and in the Granville Ophthalmology Center, were retrospectively included. Eyes implanted with the iris claw lens (Artisan Aphakia IOL model 205, Ophtec BV, Groningen, The Netherlands) were included in group 1, and eyes implanted with a newly developed sutureless trans-scleral plugs fixated lens (STSPFL, Carlevale lens, Soleko, Pontecorvo, Italy) were included in group 2. Results. Twenty-two eyes of 22 patients were enrolled in group 1, and twenty eyes of 20 patients in group 2. No difference was found in visual acuity between two groups (0.35 +/− 0.29 logmar for group 1 and 0.23 +/− 0.51 logmar for group 2) (p = 0.15) at mean post-operative follow up (6.19 +/− 3.44 months for group 1 and 6.42 +/− 3.96 months for group 2) (p = 0.13). Both the mean refractive error (MRE) and induced astigmatism (IA) were greater in group 1 compared to group 2, respectively: the MRE was 0.99 +/− 0.57 vs. 0.46 +/− 0.36 (p < 0.01), and IA was 1.72 +/− 0.96 vs. 0.72 +/− 0.52 (p < 0.01). Conclusions. No significant differences in terms of the recovery of visual acuity were found between the two groups. Group 2 (STPFL) gives better results in our sample due to less post-operative induced astigmatism and less refractive error.

Removal of Silicon Oil from the Vitreous Cavity via the Anterior Chamber. Eight Years of the Author’s Experiences

Purpose: To evaluate usefulness and safety of removal of silicone oil from the vitreous cavity via the anterior chamber.&#x0D; Methods: The procedures were performed between 2012 and 2020 in 31 patients who required endotamponade with the use of light silicone oils. In most of the patients, the procedure was combined with cataract removal, secondary lens implantation or transscleral fixation of an artificial lens. A passive bimanual technique was used to replace silicone oil with fluid.&#x0D; Results: The procedure to remove silicon oil via the anterior chamber proceeded without serious intra- and postoperative complications. There were no hypotony observed in first postoperative day.&#x0D; Conclusion: Patients eligible for the procedure are those who have preoperative indications for silicone oil removal and whose removal path via the anterior chamber is not associated with a special need to remove the lens from the eye.

Party Poppers and Balloons: Fun and Games or Lives and Limbs?

Abstract&#x0D; We report two cases of ocular trauma caused by recently popular party poppers and LED balloons, commonly used in parties nowadays. One case depicted a closed globe injury as a result of a party popper spray over the eye. The pressure of the spray resulted in a blunt trauma causing full thickness macular hole which was later treated with Pars Plana Vitrectomy (PPV) surgery. The second case is an example of an open globe injury caused by the bursting of LED balloon over the eye of a young child resulting in corneal perforation, traumatic cataract, vitreous hemorrhage with an intraocular foreign body (IOFB). It was successfully treated with corneal suturing, lens extraction, PPV surgery and removal of IOFB followed by a secondary lens implantation. Both of the sustained injuries were completely avoidable hence emphasizing the requirement of eye safety awareness programs and diligence in the use of these gadgets in everyday lives.

Visual outcome and surgical results in children with Marfan syndrome.

ImportanceTo determine visual and surgical results in children with Marfan syndrome.BackgroundMarfan syndrome involves ocular complications which can lead to visual disturbance and amblyopia. Data about the visual and surgical results in children with Marfan syndrome is vital for the clinical management of these patients.DesignRetrospective data analysis.ParticipantsEighty‐two eyes of 41 patients with a genetically proved diagnosis of Marfan syndrome.MethodsMedical records of patients with Marfan syndrome were reviewed between 2007 and 2017. Ocular complications, visual acuity (VA) of patients with/without lensectomy and surgical method were evaluated.Main Outcome MeasuresVA outcomes of patients with Marfan syndrome with/without surgical repair of ectopia lentis.ResultsIn 27 (66%) of the 41 patients a bilateral subluxation of the lens was visible and 14 (52%) patients received lensectomy. The mean age at initial presentation was 12.3 ± 9 years and mean follow‐up was 3 years (range 1‐7). VA varied from 1.2 to −0.1 logMAR at first examination. At initial presentation, mean VA was 0.1 ± 0.7 logMAR in patients with a normal lens status (n = 14) and 0.3 ± 0.5 logMAR in patients with subluxation of the lens (n = 27) (P < .01). VA improved from 0.2 ± 0.5 logMAR to 0.1 ± 0.5 logMAR (P = .06) in children with subluxation of the lens who did not need a lensectomy (n = 12) and from 0.5 ± 0.5 logMAR to 0.2 ± 0.5 logMAR (P = .02) in patients who were referred to lensectomy with/without secondary lens implantation.Conclusions and RelevanceIn Marfan syndrome subluxation of the lens was found in the majority of children. Improvement of VA resulted in children with subluxation of the lens and following lensectomy.

International Practice Patterns for the Management of Acute Postsurgical and Postintravitreal Injection Endophthalmitis: European Vitreo-Retinal Society Endophthalmitis Study Report 1

To study the practice patterns for the management of acute postoperative and postinjection endophthalmitis. Retrospective, interventional, nonrandomized, multicenter study. Data on 237 eyes diagnosed with acute endophthalmitis occurring after intraocular surgery or procedures provided by 57 retina specialists from 28 countries. Rates of pars plana vitrectomy (PPV), repeat intravitreal injection, and adjunctive therapeutic regimens (local and systemic antibiotics and steroids). Of 237 analyzed eyes, acute endophthalmitis secondary to cataract surgery or secondary lens implantation represented 64.6% of cases (153 eyes), whereas the remaining were secondary to intravitreal injections (35 eyes [14.8%]), PPV (29 eyes [12.2%]), and other intraocular surgeries (20 eyes [8.4%]). All eyes received intravitreal antibiotics on the same day of diagnosis. Overall, early PPV was used within the first week of presentation in 176 eyes (74.3%). There was no statistical difference in the proportion of eyes requiring a second intravitreal injection of antibiotics whether the eye was managed primarily with intravitreal antibiotics alone versus early PPV plus intravitreal antibiotics (29.5% [18 eyes] vs. 25.0% [44 eyes], respectively). Adjunctive therapies in the form of intravitreal steroids, systemic steroids, and systemic antibiotics were used in 25.3%, 21.9%, and 66.6% of eyes, respectively. The absence of disc or macular view and absence of endophthalmitis after cataract surgery were associated with an increased likelihood for early PPV (odds ratios 4.1 and 5.1, respectively). Pars plana vitrectomy was frequently performed regardless of the presenting vision in eyes with endophthalmitis after cataract surgery and intravitreal injections. Increased vitreous opacification was associated with a higher probability for performing PPV.

Funkcja widzenia po obuocznym wszczepieniu wtórnym soczewki, wykonanym 18 lat po usunięciu zaćmy wrodzonej u pacjenta z zespołem różyczki wrodzonej

Comparison of a quality of vision and changes in a everyday function in 18 years old patient with congenital rubella syndrome and concomitant nystagmus who was undergoing onetime secondary implantation of intraocular lenses. A congenital cataract extraction has been done in the first years of his life. An eye defect of high hyperopia was a consequence of postoperative aphakia and has never been corrected before. A lack of cooperation from the patient was a consequence of mental retardation. Secondary lens implantations have been done to the sulcus, onetime to the both eyes. The procedure was done under total anaesthesia. An electrophysiology examinations were taken before and 24 months after the surgery. A total change in behavior and also an improvement of cognitive abilities which was accompanied by retinal response observed in electrophysiology examinations has been achieved after correction of high hyperopia by secondary lens implantation gained due to correction of both eyes. Correction of high hyperopia caused by postoperative aphakia after removal of congenital cataract resulted in improvement of vision quality, despite long-term, over ten years of absence of any correction of this defect. Obtaining this improvement effect should be an incentive to consider secondary implantation in every case, especially when the other senses (hearing) and communication organs (speech) are also disturbed, regardless of the period of non-correction.

Methods of fixation of intraocular lenses according to the anatomical structures in trauma eyes.

Ocular trauma can lead to severe visual impairment and morbidity, depending on the anatomical structures affected. The main causes of ocular trauma include foreign bodies, impact by an object, falls, and chemicals. Most ocular traumas occur in children or young male adults. A meticulous slit lamp examination is crucial for assessing all anatomical structures. Trauma to the crystalline lens can result in dislocation, an intralenticular foreign body, cataract, fragmentation, and capsular breach. An intraocular lens (IOL) can endure subluxation or luxation under the conjunctiva, into the anterior chamber or the vitreous, or can be extruded. The surgical approach depends on the condition and morphology of the lens and the anatomical structures surrounding it. If there is capsular bag support, a secondary IOL can be placed in the sulcus using remnants of the damaged capsule. If there is no capsular bag support, a secondary IOL can be fixated to the anterior chamber angle, to the iris, or to the sclera. A detailed history of injury cannot always be obtained in trauma settings. Proper education, supervision, and certified safety eye protectors could prevent up to 90% of ocular injuries. Lens trauma can be treated with various surgical procedures and fixation techniques, which nevertheless require advanced surgical skills owing to the fine anatomical structure of the anterior segment. A careful surgical strategy should be established for a globe reconstruction after trauma with secondary lens implantation. Clin. Anat. 31:6-15, 2018. © 2017 Wiley Periodicals, Inc.

Afak Hastalarda Retropupiller İris Kıskaçlı Lens ile Skleral Fiksasyonlu Göz İçi Lens İmplantasyonu Sonuçlarının Karşılaştırılması

Objective: The aim of the study was to compare outcomes following the use of retropupillary iris-claw lenses (ICLs) and scleral fixated intraocular lenses (SFIOLs) in aphakic patients after cataract surgery. Material and Methods: Nineteen eyes with secondary lens implantation were included in this study. The best corrected visual acuity (BCVA) was measured preoperatively. The anterior segment was evaluated using slit lamp biomicroscopy and dilated fundus examination was performed. Intraocular pressure (IOP) was measured. Central macular thickness (CMT) was determined with the RTVue-100® Fourier-Domain Optical Coherence Tomography (Optovue Inc, Fremont, USA). Endothelial cell count was evaluated using CellChek XL® specular microscopy (Konan Medical, Hyogo, Japan). The measurements were repeated in the first week, first month, and at three months, postoperatively. Results: Sixty-three per cent of the study participants were men, with a mean age was 68.11 years. A statistically significant difference was not observed between the two groups with regard to BCVA and IOP. The increase in CMT in the first week and first month was statistically significant in the group in whom retropupillary ICL were implanted. Endothelial cell loss was 9.77±3.93% in the retropupillary ICL group and 6.51±4.74% in the SFIOL group. One patient in each group developed an epiretinal membrane. Cystoid macular edema (CME) was detected in one patient who underwent retropupillary ICL implantation. Conclusion: Both retropupillary ICL and SFIOL implantation were found to be successful and safe in aphakic patients. A statistically significant difference was not observed between the two groups regarding endothelial cell loss over short-term follow-up. An increase in CMT was detected early period in the retropupillary ICL cases.

Preoperative Evaluation of Cases with Aphakia and Intraocular Lens Dislocation by Ultrasound Biomicroscopy

The purpose of this study is to evaluate the capabilities of ultrasound biomicroscopy (UBM) as a diagnostic method for surgical planning of secondary intraocular lens (IOL) implantation in aphakia and intraocular lens dislocation. In this retrospective study, 19 eyes of 19 patients with aphakia and IOL dislocation that was not possible to evaluate by biomicroscopy because of the causes like corneal edema, opacity, anterior chamber reaction, ectopic pupil or poor pupil dilatation following cataract surgery were included. Ultrasound biomicroscopy was performed preoperatively to determine the capsule integrity, degree of ciliary sulcus support and iridocapsular adhesions. Seven patients with aphakia and 12 patients with posterior chamber IOL following cataract surgery were studied. Ultrasound biomicroscopy revealed that 4 of 7 eyes with aphakia had adequate capsule integrity (two eyes also had iridocapsular adhesions) and ciliary sulcus support, and 3 eyes had inadequate capsular remnant. Sulcus-supported posterior chamber IOLs were implanted in 4 eyes, and scleral-fixated posterior chamber IOLs were implanted in 3 eyes. Ultrasound biomicroscopy showed that 4 of 12 eyes with IOL dislocation had adequate capsule remnant, and there was no adequate capsular remnant and ciliary sulcus support in 8 eyes. IOL reposition or IOL exchange were performed in 4 eyes and IOL exchange and scleral-fixated posterior chamber IOLs implantation or scleral fixation of dislocated IOLs were performed in 8 eyes. In conclusion, ultrasound biomicroscopy helps the surgeon to select the appropriate surgical protocol by determining the capsule integrity, implant bed and iridocapsular adhesions preoperatively. It is also useful to choose the IOL model and its fixation type.

Sekundäre Intraokularlinsenimplantation von Sklera-nahtfixierten Intraokularlinsen

Scleral suture fixation is one of several techniques used for secondary lens implantation in cases of inadequate capsular support for which many variations have been published. A transscleral suture can be accomplished using either an external or internal approach. The lens can be implanted using an injector with large incisions for unfolding lenses or also via small self-sealing incisions. Episcleral fixation of the suture can be accomplished by protecting the knot under scleral flaps, intrascleral rotation of the knot and using sclerocorneal pockets or scleral grooves. The intrascleral Z-suture with five intrascleral passes of the suture is a knotless technique providing several advantages.

Analysis of outcomes of secondary intraocular lens implantation in open-globe injury after vitrectomy

To explore the time and method of secondary intraocular lens (IOL) implantation in open-globe injury after vitrectomy and to analyze the efficacies and relative factors of the treatment. This is a retrospective case series study. Clinical data of 78 eyes of 78 patients with open-globe injury who underwent secondary IOL implantation after vitrectomy in Tianjin Medical University General Hospital from 2007 to 2012 were analyzed. There were 27 eyes of 27 patients with penetrating injury, 36 eyes of 36 patients with intraocular foreign body (IFB), 4 eyes of 4 patients with ocular rupture, and 11 eyes of 11 patients with endophthalmitis. The IFB included magnetic foreign body in 23 eyes of 23 patients, glass foreign body in 6 eyes of 6 patients, and eyelash foreign body in 7 eyes of 7 patients. Thirty-one eyes of 31 patients were tamponadewith silicone oil, and 47 eyes of 47 patients were tamponadewith C3F8 during vitrectomy. The methods of IOL implantation included posterior chamber IOL implantation in 32 eyes of 32 patients and sulcus-fixed IOL implantation in 46 eyes of 46 patients. The examinations before IOL implantation mainly included visual acuity, slit lamp biomicroscope, direct and indirect ophthalmoscope, visual electrophysiology, corneal endothelium, B scan, ultrasound biomicroscope and intraocular pressure. Four eyes of 4 patients underwent suturing of peripheral iris, and 5 eyes of 5 patients underwent suturing of iris laceration. The visual acuity ranged from light perception to 0.1 before vitrectomy. The mean follow-up time was 15 ± 3 months with a range from 6 to 36 months. The mean interval between IOL implantation and vitrectomy was 2.5 ± 0.2 months with a range from 1.5 to 6 months. The best corrected visual acuity was from 0.1 to 1.0 after vitrectomy. The uncorrected visual acuity ranged from 0.1 to 0.8, and the best corrected visual acuity was from 0.1 to 1.0 after IOL implantation. The postoperative complications mainly included mild anterior chamber exudates in 4 eyes of 4 patients, temporary intraocular pressure elevation in 7 eyes of 7 patients, and recurrent retinal detachment in 2 eyes of 2 patients. The appropriate interval of secondary IOL implantation in open-globe injury after vitrectomy is important. Posterior chamber IOL implantation is performed in eyes with integrity of posterior capsule, and IOL sutured in the sulcus in eyes without posterior capsule support. It is safe and effective for secondary IOL implantation in open-globe injury after vitrectomy.
